Firstly I don't like the packaging as the primer leaked out and made quite a mess in my bag. I now only store it lid-up to prevent leaking and can't use it while travelling.

As far as priming goes: it does help your foundation to go on a lot smoother. It has a very silky feel. Unlike my Clinique Pore Minimiser primer, this one doesn't dry out the skin. I didn't find that it prevented oilyness on my skin but I wasn't exactly disappointed because I mainly use my to create a smooth canvas for foundation.

For my eyelids personally this was way too greasy to prevent creasing so I wouldn't recommend it for that. I also noticed that it cloggs the pores a lot as it is silicone based. I try to use clay masks at least twice a week to prevent breakouts from this primer.

If you have some cash to spare, I would recommend trying it out, but if you are looking for a very high quality primer, in my opinion there are better ones out there....
